Ta, Ti and Hf effects on NbSn high-field performance: temperature-dependent dopant occupancy and failure of Kramer extrapolation
Chiara Tarantini, Shreyas Balachandran, Steve M Heald +5
The increasing demand for improving the high-field (16-22 T) performance of NbSn conductors requires a better understanding of the properties of modern wires much closer to irr…

Beneficial influence of Hf and Zr additions to Nb4at.%Ta on the vortex pinning of NbSn with and without an O source
Shreyas Balachandran, Chiara Tarantini, Peter J. Lee +5
Here we show that addition of Hf to Nb4Ta can significantly improve the high field performance of NbSn, making it suitable for dipole magnets for Future Circular Collider (FC…

Revealing the role of nitrogen on hydride nucleation and stability in pure niobium using first principles calculations
P. Garg, S. Balachandran, I. Adlakha +3
Niobium provides the basis for all superconducting radio frequency (SRF) cavities in use, however, hydrogen is readily absorbed by niobium during cavity fabrication and subsequent…
